Title: Tape player driving device
Inventor: OKADA HITOSHI
IPC: G11B15/44
Filed: 1986-07-03
Abstract: PURPOSE:To convert a winding torque into a set value by providing a friction gear to a driving device for a tape player. CONSTITUTION:A motor output whose rotating speed is kept in a constant state (fast winding speed) is transferred to a driving gear 1, and at the time of fast winding the large diameter 1a of the driving gear 1 is made to lock to a fast winding side link gear 3, from which it is transferred to a small diameter 5a of a reel driving gear 5 so as to wind the tape at a high speed. And at the time of playing back the motor output at fast winding speed is made to lock to a play side link gear 4 from the small diameter 1b of the driving gear 1 by the switching link 2 and transferred to the upper gear 6a of a friction gear 6 from the play side link gear 4. In the friction gear 6 between the upper gear 6a and a lower gear 6b frictional force in a constant value is acted by a spring 7, so the upper gear 6a and the lower gear 6b are made to slide and the rotating speed of the lower gear 6b is delayed to attenuate the motor rotating speed and torque, so that the tape can be winded at a low speed.

Abstract: PURPOSE: To design the realization of a superconducting magnet having a high critical temperature by making a thin film with one of the materials of diamond, boron nitride, sapphire, zirconia, and tungsten carbide and forming on it a superconducting film of oxide.  
     CONSTITUTION: On a copper tape 1 of a thickness 10μm and a width 10mm is formed a diamond film 2 of a thickness 10μm by means of plasma CVD process, etc. Further on it is formed a film of oxide superconductor of a thickness 100μm by means of sputter process, etc. Further depositing about 1μm thickness of insulation film of SiO 2  or the like, a flexible multi-layer tape is made. This tape is used as a conductor coil of a superconducting magnet. Applying current below a critical temperature, magnetic field of 50tesla or more can be generated. Since the stress occurring in the longitudinal direction of the tape is below the strength of the diamond film even if the magnetic field exceeds 100tesla, the magnet is not destroyed.

Abstract: PURPOSE:To reduce crystal defects generated in the main surface part by activating an ion implanted layer formed in the main surface part of a semiconductor substrate by annealing it by irradiation with infrared rays under the condition that a gas having a good heat transfer efficiency is introduced. CONSTITUTION:In a vacuum chamber 1, projection of infrared rays from a infrared ray lamp 3 to a semiconductor substrate 50 is controlled by opening and closing a shutter 4. While introducing H2 gas from an H2 gas supply source 7a through a gas flow meter 6a, open-close valve 5a, and a gas introducing pipe 1b, activation of the ion implanted layer formed in the main surface part of substrate 50 is done. Non-uniformity of temperature generated in the main surface part of substrate 50 is alleviated by the H2 gas of good heat transfer efficiency. The thermal stress generated in the main surface part of substrate 50 is diminished and generation of crystal defects is reduced. The same effect can be obtained by introducing He gas or a mixed gas of H2 and He from an He gas supply source 7b.
